Detailed Description

This HELLA MAF sensor is engineered to measure incoming air volume so the engine management system can calculate fuel delivery with greater precision. For Nissan Frontier and Nissan Xterra models, that means cleaner signal input, more stable idle quality, and better throttle consistency when the original sensor is worn or contaminated. The 358166121 replacement is also listed for Nissan Pickup applications, including 1996 models from 01/1996 and 1997 models.

HELLA’s electronics expertise is reflected in the sensor’s OE-style fit and signal accuracy. If you are searching for a Nissan Frontier mass air flow sensor, Nissan Xterra MAF sensor, or a direct replacement for part number 358166121, this unit matches the required bolted configuration and 3-connector layout.

What It Helps Address

• Rough idle caused by inaccurate airflow readings
• Hesitation or poor throttle response
• Incorrect fuel mixture from a failing MAF sensor
• Reduced fuel economy from unstable air metering
• Check engine light concerns related to airflow signal faults

Installation Notes

Verify the mounting type is bolted and confirm the connector count is 3 before installation. Clean the intake tract and inspect the air filter housing, wiring connector, and intake ducting so the new sensor is not affected by contamination or air leaks. Always match the vehicle application by year, make, model, and engine configuration before ordering.
